Nasa puts out call for space taxis

Cape Canaveral - Despite budget uncertainties, Nasa on Tuesday issued a solicitation for a commercially operated space taxi to ferry astronauts to the International Space Station, an attempt to break Russia's monopoly on crew transport by 2017. The United States has been without a human space transportation system since 2011 when Nasa retired its three-ship shuttle fleet due to high operating costs and fundamental safety questions. Nasa's so-called Commercial Crew program is intended to address both cost and safety concerns, as well as return the capability to fly people to space from US soil. The agency wants to be able to purchase rides on a commercial basis before the end of 2017 to fly four crewmembers to and from the station about every six months. The new solicitation asks for proposals for final design, development, test, evaluation and certification of a human space transportation system, including ground operations, launch, orbital operations, return to Earth and landing. Rather than designing a replacement space shuttle and hiring contractors to build it, Nasa decided to partner with industry, offering money, technical advice and oversight.
